Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This Application claims priority to and benefit under 35
U.S.C. .sctn.119(e) of U.S. Provisional Patent Application No.
62/261,155 filed Nov. 30, 2015, which is hereby incorporated by
reference herein in its entirety as if fully set forth below.
FIELD OF THE INVENTION
[0002] The presently disclosed subject matter relates generally to
tennis training devices for improving a variety of tennis swings.
Specifically, the presently disclosed subject matter relates to
tennis swing timing devices, forehand groundstroke devices, and
groundstroke preparation devices.
BACKGROUND
[0003] Proper tennis swings require a balancing of opposing forces.
On one hand, tennis swings are rotational, with a player's hips
providing the rotation. On the other hand, tennis swings exist
upwards and downwards on a vertical plane. To achieve these forces
together, the player must remain relaxed, let gravity take the
weight of the racket, and properly time the beginning of hip
rotation with the upper body. In other words, to hit a proper
tennis swing, the player must use her body on the forward swing in
a specific, timed sequence, beginning with the hips and then
continuing through the upper body, arm, wrist, hand, and finally
the racket. Proper timing then ensures the racket is in the proper
position to obtain correct downward and upward vertical motion of
the swing.
[0004] Yet, proper tennis swing technique is not intuitive, even
for exceptional athletes. Where proper technique requires using the
correct muscles in a well-timed sequence, starting with the lower
body, beginning players often use only their arms to hit with the
racket. In some instances, beginning players may engage in
"reaching back" or "dropping down" with their arms during
preparation and initiating the forward swing with their upper body.
Hitting the ball this way is often instinctive for beginning
players as using the upper body and the arms is a reliable way to
make contact with a moving tennis ball while navigating the court
quickly. However, using the upper body and arms to hit the ball
rather than the hips and legs can negatively affect a player's
movement, resulting in less control and power throughout the
swing.
[0005] Known tennis training devices seek to correct body angles
during a tennis swing instead of improving body synchronization
during the swing. Additionally, other devices operate as a crutch,
lacking the flexibility to allow the player to develop proper body
positioning on her own.
[0006] Accordingly, there is a need for tennis training devices to
address the above-mentioned deficiencies. Embodiments of the
present disclosure are directed to these and other
considerations.
SUMMARY
[0007] Briefly described, embodiments of the presently disclosed
subject matter relate to systems and devices for improving tennis
swing timing and preparation. In some embodiments of the present
disclosure, a tennis training system can comprise a first band
adapted to be worn on an upper portion of a wearer's first arm and
a second band adapted to be worn on a lower portion of the wearer's
first arm. The system can comprise a first sleeve and a second
sleeve affixed to the first and second band. For instance, the
first sleeve can have a first end and a second end with the first
end affixed to the first band and the second sleeve can oppose the
first sleeve, and the second sleeve can have a first end affixed to
the second band. Additionally, the system can comprise an inner
tubing that can extend substantially between the first end of the
first sleeve and the first end of the second sleeve.
[0008] The first sleeve and the second sleeve can each house a
magnetic component. For instance, a first magnetic component can be
disposed within the second end of the first sleeve and a second
magnetic component can be disposed within the second end of the
second sleeve. The first and second magnetic components can be
configured to transition the first and second sleeves from an
unconnected state, in which at least a portion of the inner tubing
is disposed between the first sleeve and the second sleeve, to a
connected state. Additionally, the tension created between the
upper and lower portions of the wearer's first arm can be at an
angle between the upper and lower portions
[0009] In some embodiments, the system and devices can comprise a
first ball connector integral to the first end of the first sleeve
and a second ball connector integral to the first end of the second
sleeve. Additionally, the first band can comprise a first socket
connector adapted to receive the first ball connector and the
second band can comprise a second socket connector adapted to
receive the second ball connector.
[0010] In some embodiments, a central portion of the first sleeve
and a central portion of the second sleeve can comprise a pliable
material and the second end of the first sleeve and the second end
of the second sleeve can comprise a rigid material. Additionally,
in some embodiments the inner tubing can comprise an elastic
material such that when the magnetic components are in an
unconnected state, the inner tubing increases in length.
[0011] When worn by a wearer, the magnetic components can be in a
connected state with the angle between the upper and lower portions
of the wearer's first arm is 90 degrees or less. Otherwise, when
the magnetic components are in an unconnected state, angle between
the upper and lower portions of the wearer's first arm is greater
than 90 degrees.
[0012] Additionally, embodiments of the presently disclosed subject
matter can relate to a forehand groundstroke device. The forehand
groundstroke device can comprise a first band, a second band, a
resistance tubing, and an extension component. The resistance
tubing can be adapted to connect between the first band and the
extension component, and the extension component can be adapted to
connect between the resistance tubing and the second band. When
worn by a wearer the first band can attach around the arm of the
wearer, the second band can attach around an upper leg of the
wearer, and the extension component can elevate the resistance
tubing proximate the waist of the wearer.
[0013] Embodiments of the presently disclosed subject matter can
relate to a groundstroke preparation device. The groundstroke
preparation device can comprise a first band, a second band, and
adherent components. The second band can comprise an insert that
extends from the second band towards the first band. When worn by a
wearer, the first band can attach around the upper arm of the
wearer, and the second band can attach around the torso of a
wearer. The adherent components can be configured to transition the
device from a connected state to an unconnected state. When in a
connected state, the adherent components can attach together, and
hold the upper arm of the wearer proximate the torso of the
wearer.

disclosed subject matter and is not intended to be reflective of
the full scope of the presently disclosed subject matter as
claimed. Additional features and advantages of the presently
disclosed subject matter are set forth in the following
description, may be apparent from the description, or may be

DETAILED DESCRIPTION
[0026] The various embodiments of the presently disclosed subject
matter are described with specificity to meet statutory
requirements. However, the description itself is not intended to
limit the scope of this patent. Rather, it has been contemplated
that the claimed subject matter might also be embodied in other
ways, to include different steps or elements similar to the ones
described in this document, in conjunction with other present or
future technologies.
[0027] It should also be noted that, as used in the specification
and the appended claims, the singular forms "a," "an" and "the"
include plural references unless the context clearly dictates
otherwise. References to a composition containing "a" constituent
is intended to include other constituents in addition to the one
named. Also, in describing the preferred embodiments, terminology
will be resorted to for the sake of clarity. It is intended that
each term contemplates its broadest meaning as understood by those
skilled in the art and includes all technical equivalents which
operate in a similar manner to accomplish a similar purpose.
[0028] Herein, the use of terms such as "having," "has,"
"including," or "includes" are open-ended and are intended to have
the same meaning as terms such as "comprising" or "comprises" and
not preclude the presence of other structure, material, or acts.
Similarly, though the use of terms such as "can" or "may" is
intended to be open-ended and to reflect that structure, material,
or acts are not necessary, the failure to use such terms is not
intended to reflect that structure, material, or acts are
essential. To the extent that structure, material, or acts are
presently considered to be essential, they are identified as
such.
[0029] It is also to be understood that the mention of one or more
method steps does not preclude the presence of additional method
steps or intervening method steps between those steps expressly
identified. Moreover, although the term "step" may be used herein
to connote different aspects of methods employed, the term should
not be interpreted as implying any particular order among or
between various steps herein disclosed unless and except when the
order of individual steps is explicitly required.
[0030] The components described hereinafter as making up various
elements of the disclosed technology are intended to be
illustrative and not restrictive. Many suitable components that
would perform the same or similar functions as the components
described herein are intended to be embraced within the scope of
the invention. Such other components not described herein can
include, but are not limited to, for example, similar components
that are developed after development of the presently disclosed
subject matter.
[0031] To facilitate an understanding of the principles and
features of the invention, various illustrative embodiments are
explained below. In particular, the presently disclosed subject
matter is described in the context of tennis training devices for
improving a variety of tennis swings. Specifically, the presently
disclosed subject matter relates to tennis swing timing devices,
forehand groundstroke devices, and groundstroke preparation
devices.
[0032] Referring now to the figures, wherein like reference
numerals represent like parts throughout the views, the connector
system will be described in detail.
[0033] Systems and Devices for Improving Tennis Swing Timing
[0034] One problem many tennis players face occurs with timing the
sequence of movements making up a tennis swing. Good timing is
imperative to strike an on-coming tennis ball with adequate pace,
spin, and depth, while maintain power and control throughout the
swing. Because proper timing in tennis is often counter-intuitive,
one or more of the tennis swing timing devices described herein can
train tennis players to learn proper swing timing. For instance,
aspects of the present disclosure can train a wearer (i.e., a
tennis player) of the device to begin a swing with her hips,
followed by her upper body, and then using the weight and momentum
of the racket to generate a proper swing. It can do so by
intervening or providing feedback to the wearer that good timing
was not achieved.
[0035] FIGS. 1A and 1B illustrate a tennis swing timing device 100
in a connected state and an unconnected state respectively, in
accordance with one or more embodiments of the present disclosure.
As illustrated in FIGS. 1A and 1B, the tennis swing timing device
can comprise a first band 105 and a second band 110. The first band
105 can be affixed to a first sleeve 125a and the second bad 110
can be affixed to a second sleeve 125b. The first sleeve 125a can
comprise a first end 115a and a second end 120a, with the first end
115a affixed to the first band 105 via a ball-and-socket attachment
130a. Similarly, the second sleeve 125b can comprise a first end
115b and a second end 120b, with the first end 115b affixed to the
second band 110 via a ball-and-socket connector 130b.
[0036] When in a connected state, and as illustrated at FIG. 1A,
the second end 120A of the first sleeve 125a can abut the second
end 120b of the second sleeve 125a. In some embodiments, the first
sleeve 124a and the second sleeve 125b can be connected via first
and second magnetic components 170a, 170b, illustrated in greater
detail with respect to FIGS. 1B and 1C. The disclosed tennis swing
timing device 100 can also comprise an inner tubing 150. As
described below in connection with FIG. 1C, the inner tubing 150
can be housed within the first sleeve 125a and the second sleeve
125b In some embodiments, the inner tubing 150 can be attached
proximate two opposing ends of the first and second sleeves 125a,
125b using two or more pin members 140, as illustrated in FIG. 1A.
For instance, the inner tubing 150 can extend substantially between
the first end 115a of the first sleeve 125a and the second end 115b
of the second sleeve 125b.
[0037] FIG. 1B illustrates a tennis swing timing device 100 in an
unconnected state, in accordance with some embodiments of the
present disclosure. As discussed in greater detail below, the first
and second magnetic components 170a, 170b can be configured to
transition the device from the unconnected state (shown in FIG. 1B)
to the connected state (shown in FIG. 1A). When in an unconnected
state, as shown at FIG. 1B, the first sleeve 125a and the second
sleeve 125b can be separated and a portion of the inner tubing 150
can be exposed between the two sleeves.
[0038] In some embodiments, the first and second sleeves 125a, 125b
can house an inner tubing 150. FIG. 1C shows a cross-sectional view
of the tennis swing timing device 100 having an inner tubing 150
housed within the first and second sleeves 125a, 125b, in
accordance with one or more exemplary embodiments. As illustrated
at FIG. 1C, the first and second sleeves 125a, 125b can be hollow
such that a channel 155 can be formed axially within the first and
second sleeves 125a, 125b. The inner tubing 150 can be disposed
within the channel 155 and attached proximate a first end 115a of
the first sleeve 125a. The inner tubing 150 can extend from its
attachment point at the first end 115a of the first sleeve 125a,
through the first sleeve 125a, and into the second sleeve 125b,
attaching in a similar manner proximate the first end 115b of the
second sleeve 125b. When in an unconnected state, as illustrated at
FIGS. 1B and 1C, at least a portion of the inner tubing 150 can be
exposed (e.g. visible) between the first sleeve 125a and the second
sleeve 125b.
[0039] As illustrated in FIG. 1C, the first sleeve 125a and the
second sleeve 125b can be releaseably connected. In some
embodiments, the first sleeve 125a and the second sleeve 125b can
comprise a first magnetic component 170a and a second magnetic
component 170b. The first magnetic component 170a and the second
magnetic component 170b can be disposed within a second end 120a,
120b of the first and second sleeves 125a, 125b. FIG. 1D
illustrates a first magnetic component 170a disposed within a
second end 125a of a first sleeve 125a, in accordance with some
embodiments of the present disclosure. In an exemplary and
non-limiting embodiment, as illustrated at FIG. 1D, the first
magnetic component 170a can be disposed axially within the second
end 165a of the first sleeve 125a. Additionally, the first magnetic
component 170a and the second magnetic component 170b can comprise
a central hole 180 through which the inner tubing 150 can extend
between the first and second sleeves 125a, 125b, as illustrated at
FIGS. 1C and 1D. Allowing the inner tubing 150 to extend through
the first and second magnetic sleeves 125a, 125b permits automatic
reconnection after the first and second magnetic components 170a,
170b break apart. In other words, the first and second magnetic
components 170a, 170b can automatically revert back to a connected
state due to the inner tubing 150 and resistance created therein.
Having automatic reconnection can be advantageous because it can
allow a player to develop proper body placement on their own
instead of relying on the training device as a crutch.
Additionally, embodiments of the present disclosure that are
automatic allow the player to hit continuously while using the
device 100. While various components are discussed in reference to
the first sleeve of the tennis swing timing device, it is
understood that the second sleeve may comprise some or all of the
components discussed with reference to the first sleeve.
[0040] The magnetic components of the tennis swing training device
can be configured to transition the device 100 from an unconnected
state to a connected state, as illustrated at FIGS. 1A-1C. The
first magnetic component 170a and the second magnetic component
170b can connect the first and second sleeves 125a, 125b together.
As will be understood by those skilled in the art, the first and
second magnetic components 170a, 170b can be held together by a
magnetic force. When the device is subjected to an external force
exceeding the magnetic force, e.g., the player's arm moves between
the first and second magnetic components 170a, 170b, the first and
second magnetic components 170a, 170b can disengage and the first
and second sleeves 125a, 125b can move apart.
[0041] As discussed above with respect to FIG. 1A, in some
embodiments, the first band 105 and the second band 110 can be
attached to the first and second sleeves 125a, 125b via
ball-and-socket attachment 130a, 130b. FIGS. 2A and 2B illustrate
an exemplary and non-limiting embodiment of a ball-and-socket
attachment 200. The ball-and-socket attachment can comprise a ball
connector 210 and a socket connector 220. In some embodiments, the
ball connector 210 can be snapped manually within the socket
connector 220. As will be understood by those skilled in the art, a
ball connector 210 can be a substantially rounded or
spherical-shaped protrusion, a surface of which that can fit into a
socket connector 220 that has a corresponding rounded depression. A
ball and socket connector 200, like that illustrated in FIGS. 2A
and 2B, can be advantageous because such a connector can provide a
nearly infinite range of motion. Therefore, for example, the first
and second sleeves 125a, 125b can have a flexible range of motion
as it moves with respect to the first and second bands 105,110.
Additionally, in an exemplary and non-limiting embodiment, the
ball-and-socket connector can provide a stronger connection than
the magnetic connection between the first and second sleeves
thereby preventing the outer tubing from disconnecting from the
first or second bands during use.
[0042] In some embodiments, and as illustrated at FIGS. 2A and 2B,
the ball connector 210 can be integral to a first sleeve 125a. As
such, the ball connector 210 can extend from the first end 115a of
the first sleeve 125a. Yet, in other embodiments, it is understood
that the ball connector 210 can be a separate part from the first
and second sleeves 125a, 125b, and therefore can be attached and
removed from the first and second sleeves 125a, 125b, as desired.
For example, the ball connector can comprise a spherical-shaped
component, a secondary tubing, and a helical threading disposed
around at least a portion of an external surface of the secondary
tubing. Similarly, the first and second sleeves can comprise a
helical threading disposed around an internal surface proximate the
second ends of the first and second sleeves. As such, the ball
connector can screw into the first sleeve, and then the ball
connector and first sleeve assembly can be coupled with the first
band. Such a configuration can be advantageous, for example,
because the outer tubing can be adjustable in size (i.e. length)
and therefore provide a universal fit for wearers of a variety of
ages, sizes, and heights. For instance, the first and second
sleeves can be adjustable wherein the secondary tubing of the ball
connector can come in a variety of lengths.
[0043] The socket connector 220 can attach to the first band 105
and the second band 110 in a variety of ways. For instance, in some
embodiments, and as illustrated at FIG. 1A, the socket connector
220 can comprise a base portion 132a, 132b and a socket component
130a, 130b. The base portion 132a, 132b can be substantially flat
and the socket component can extend from the base portion, forming
a single unitary piece. Additionally, the base portion 132a, 132b
can be attached to the first band 105 and the second band 110. The
base portion 132a, 132b can be attached to the first and second
band 105, 110 in a variety of ways, including, but not limited to,
adhesive, stitching, welding, or other forms of bonding. For
instance, in an embodiment comprising stitching, and as illustrated
at FIG. 1A, the base 132a, 132b can comprise one or more slots
disposed proximate the side edges of the base, and a portion of the
band can be inserted within the slot, looped, and stitched over to
secure the base to the band.
[0044] The described tennis swing timing devices can be
advantageous as the first and second sleeves and the inner tubing
can be replaced or interchanged with new components or different
size and length components without having to obtain an entirely new
device. In some embodiments, the first band and the second band may
be adjustable so as to fit a variety of wearers. For instance, the
first band and the second band can comprise a hook and loop
fastener (e.g., Velcro), a plurality of snaps, or a strap and
buckle, for fastening the bands around a body part of the wearer.
In other embodiments, the first and second band may comprise
elastic bands that can stretch and conform around a wearer's arm or
other body part.
[0045] The first band and the second band can comprise any material
that can provide an adequate fit and comfort while not sliding
during use. For instance, the bands can comprise a pliable,
relatively inelastic external material and a gripping material
provided on the interior. A gripping material can comprise, for
example, any material with or adapted to have a high coefficient of
friction. Therefore, the material that will make contact with the
wearer's skin or clothing can limit sliding of the first and second
bands during use. In other embodiments, the band may comprise an
elastic material so as to stretch to fit a variety of wearers but
also fit snuggly upon application to a wearer's body. Additionally,
in some embodiments the first band and the second band can be the
same size, but need not be, depending on design preferences.
[0046] The first and second sleeves may comprise any material
having enough pliability to facilitate movement while being durable
enough to not rip easily during use. For instance, the first and
second sleeve can comprise a pliable material. In other
embodiments, the first and second sleeve can comprise a rigid
material. Still, in some embodiments, the first and second sleeve
may comprise both a pliable material and a rigid material. For
instance, a first ends 115a, 115b of the first and second sleeves
125a, 125b can comprise a rigid material while a central portion
117a, 117b of each sleeve can comprise a pliable material. As such,
the rigid material can be inserted within the pliable material and
glued so as to create a dual-material sleeve. As will be
understood, the first and second sleeves can be manufactured using
a variety of manufacturing process including, but not limited, to
3D-printing and molding, for example, injection molding.
[0047] The inner tubing can comprise any resilient, highly elastic
tubing. For instance, the inner tubing can comprise surgical
tubing. Having an elastic inner tubing can allow for the inner
tubing to stretch responsive to movement of the body parts
associated with the first and second bands and also provide for
separation of the first and second sleeves. For instance, a force
applied to the inner tubing can cause it to stretch and build
tension. When the external force applied to the magnetic components
exceeds the magnetic force between them, the magnetic components
will detach and the inner tubing can continue to stretch and build
tension. The inner tubing can then retract or relax allowing for
the two magnetic components to come together and reconnect. Such a
mechanism can provide for automatic reattachment of the magnetic
components.
[0048] The inner tubing can be any diameter including, but not
limited to, 1/8-inch, 1/4-inch, 5/16-inch 3/8-inch, and 1/2-inch.
The inner tubing can be any length so as to fit within the first
and second sleeve. Additionally, the inner tubing can be attached
to the outer tubing and the first and second bands in a variety of
ways. In some embodiments, as illustrated at FIGS. 1A-1D, the inner
tubing 150 can be fixed to the first and second sleeves, 125a,
125b. Affixing the inner tubing 150 to an interior of the first and
second sleeves 125a, 125b can allow for removal of the inner
tubing. For instance, one or more pinholes can be drilled into the
first sleeve 125a and the second sleeve 125b. The a first end of
the inner tubing can be pinned using pin member 140a proximate the
first end 115a of the first sleeve 125a and a second end of the
inner tubing can be pinned using pin number 140b proximate the
first end 115b of the second sleeve 125b. In other embodiments, the
inner tubing can be attached directly to the first band and the
second band. For instance, the inner tubing can attach to the first
and second bands through a ring. Once looped through the ring, the
inner tubing can be tied to itself. In other embodiments, the inner
tubing can be pulled through the pinhole of outer tubing and
knotted. One or more of the embodiments discussed above can allow
the inner tubing to be removable and therefore replaceable. For
instance, after some time the inner tubing may lose its elasticity.
Having a way to remove the inner tubing from the first and second
sleeve can allow for the old tubing to be replaced by new
tubing.
[0049] As discussed above, the releasable connector can comprise
two opposing magnetic components. In some embodiments the magnetic
components can comprise neodymium magnets. It is understood that,
the magnets should be large enough to apply enough adherence while
not being so big as to cause the device to weigh too much. In some
embodiments, the described tennis training device may comprise a
component for weakening the connection between the magnetic
components. Depending on the strength of the user, the magnetic
components may be too strong or too weak. Therefore, it can be
desirable to provide adjustability to the magnetic component. For
instance, in some embodiments, a component can be added between
proximate the first ends of each sleeve so as to limit the magnetic
connection between the two components. The component may include a
plastic insert that can be screwed onto each sleeve so as to
prevent the two magnetic components from directly abutting each
other. In other embodiments, the component may include various
magnetic connectors having a variety of strengths that can be
removed and replaced as desired.
[0050] It is understood that instead of being automatic, the device
can require manual reassembly. For instance, in some embodiments,
the tennis training device can comprise opposing hook and loop
straps (e.g. Velcro straps) joining the first band and the second
band. During the swing, for example, the hook and loop straps can
disconnect and subsequently be reassembled manually by the
wearer.
[0051] In another embodiment, the tennis swing timing device 100
can comprise an additional component to permit for adjusting the
size of the device to accommodate a variety of wearers. The
additional component can comprise an inelastic band comprising a
plurality of holes. The inelastic band can be adapted to connect
between the first band and the second band. The first and second
sleeves can attach to the inelastic band in one or more of the
plurality of holes. For instance, the first and second sleeves may
comprise an additional screw member for inserting within one or
more of the plurality of holes. Therefore, the first and second
sleeves can be attached at various positions along the inelastic
band. When the first and second sleeves are in a connected state,
the inelastic band may be folded and when the first and second
sleeves transition to an unconnected state, the inelastic band may
straighten out to accommodate movement of a wearer's arm.
[0052] In other embodiments, the tennis training device 100 may
require manual assembly. For instance, in one embodiment, the
tennis training device can comprise two Velcro straps between the
first and second bands. The first Velcro strap can be attached to
the first band and the second Velcro strap can be attached to the
second band. When in a connected position, the first Velcro strap
can be connected to the second Velcro strap. As described above,
the first Velcro strap can disconnect from the second Velcro strap.
In another embodiment, the tennis training device can comprise a
wrist band and Velcro tape on the racket with a Velcro strap
joining the wrist and the racket of the wearer. The tape can be
placed anywhere on the racket. In some embodiments, however, the
Velcro tape is located below the base of the string bed of the
racket.
[0053] In some embodiments, the tennis training device can comprise
an add-on. The add-on can address a situation where the wearer
pulls her elbow back behind her body during the swing. The add-on
can comprise a hard, flat, inelastic component. In some
embodiments, the component can attach either on the back of the
shoulder or the top of the upper arm. During the swing, the add-on
may contact the back of the shoulder or the top of the upper arm if
the wearer tries to pull her elbow back, thereby preventing the
wearer from pulling her elbow back behind her body during the
swing.
[0054] In view of the tennis swing timing devices discussed above,
embodiments of the present disclosure can also comprise a system
for improving a wearer's tennis swing timing, as illustrated at
FIGS. 3A-3C Like the devices discussed previously, the system can
comprise a first band 305 and a second band 310. The first band 305
is adapted to be worn on an upper portion of a wearer's first arm
and the second band 310 is adapted to be worn on a lower portion of
the wearer's first arm. As discussed above, a first sleeve 325a and
a second sleeve 325b can be affixed to the first band 305 and the
second band 310. An inner tubing can be housed within the first and
second sleeves 325a, 325b and extend from about a first end of the
first sleeve 325a to about a first end of the second sleeve 320, as
discussed above. Additionally, as discussed previously, the outer
tubing 320 can comprise a first sleeve 325a releaseably connected
to a second sleeve 325b via a first magnetic component and a second
magnetic component. The first and second magnetic components can be
configured to transition the first and second sleeve 325a,325b from
a connected state 300a to an unconnected state 300b, as illustrated
at FIGS. 3A-3C. As seen at FIG. 3C, when the magnetic components
are in an unconnected state 300b, at least a portion of the inner
tubing 330 is exposed between the first sleeve 325a and the second
sleeve 325b. As discussed above with respect to FIGS. 2A and 2C, in
some embodiments, the system can comprise a first ball connector
345a integral to the first end of the first sleeve 325a, and a
second ball connector 345b integral to the first end of the second
sleeve 325b. Additionally, the system can comprise a first socket
connector 340a adapted to receive the first ball connector 345a and
a second socket connector 340b adapted to receive the second ball
connector 345b.
[0055] When in a connected position, the first and second sleeves
325a, 325b can be attached between the forearm and the upper arm,
holding the arm at about a 90-degree angle, as shown at FIG. 3B.
When the arm is extended, or moved to an angle exceeding 90
degrees, tension caused by the extension can in turn cause the
inner tubing to stretch and the magnetic components to disconnect,
as illustrated at FIG. 3C. When the arm is brought back to about a
90-degree angle, the inner tubing can retract and the first and the
magnetic components can re-connect, thereby providing automatic
reconnection of the device. As will be understood, the system can
comprise some or all of the features discussed previously with
respect to the tennis swing timing devices.
[0056] In another embodiment, a similar connection can be created
between the wrist and racket. The first band can attach around a
wrist of the wearer and the second band can connect to the racket
with the first and second sleeves joining the wrist to the racket.
As will be understood, movement of one body part with respect to
the other can affect the state of the device, changing it from a
connected to an unconnected state and vice versa.
[0057] Various embodiments of the present disclosure can be used
for assistance in a variety of tennis swings including the forehand
groundstroke, the backhand groundstroke, the two-handed backhand,
the serve, and the backhand splice. Embodiments for each stroke
will be discussed in more detail below.
[0058] Embodiments of the present disclosure can assist a player
with managing her arm placement and timing during forehand
groundstroke preparation. In some embodiments, systems and devices
for improving tennis swing timing and preparation can prevent the
player from overusing her arms during preparation by providing the
player with feedback that her arms are in an improper position. The
significance of maintaining proper arm placement before a player
starts rotating her hips to begin the swing is that the player's
arm remains sufficiently bent with the racket in line with the hand
so that the force from the hip rotation will generate downward
motion of the arm and racket on its own accord. That is, the hip
rotation, gravity, and the weight and momentum of the racket can
generate the downward motion. Moreover, such assistance can occur
even when the ball is low. The player can be coerced into
generating continued downward motion in her arm and racket after
she starts to swing with her hips. Because the ball is well below
hand-level when the player starts to swing, she has to let the
downward motion continue to make contact.
[0059] When assisting a player with forehand groundstroke
preparation, the systems and devices can provide feedback to the
player if she drops her hand down before executing the swing. For
instance, if the player is overusing her arms in her stroke
preparation, the feedback can comprise detachment of the first
magnetic component from the second magnetic component. Therefore,
during training, the player must work to maintain the magnetic
connection between the magnetic components. The player must
maintain proper racket and hand height until the player starts
swinging from the hips, otherwise the first and second magnetic
components will detach, indicating that the player lost proper
racket and hand height.
[0060] In some embodiments, when worn by a player to improve the
forehand groundstroke technique, the described systems and devices
can be worn as discussed above with respect to FIGS. 3A-3C. When in
use, the tennis training device can hold the upper arm and forearm
at approximately a 90-degree angle. When the player straightens out
her arm, the two magnetic components holding the angle between the
upper arm and forearm can disconnect thereby providing feedback to
the player that the arm is starting to straighten out. When
preparing for a forehand groundstroke, the player must follow a
direct sequence of events to execute a properly timed forehand
groundstroke. At the same time, the player must maintain proper arm
placement during preparation, e.g. before the player starts to
swing with her arm. Therefore, for instance, the device can hold
the player's arm at the proper angle, less than or equal to
90-degrees, up and until the player rotates her hips and upper
body. Then, the player may extend her arm following through with
the swing with the racket coming in contact with the ball. If the
player extends her arm too soon during the preparation, the two
magnetic components will disconnect thereby providing the player
with feedback that she has lost proper timing and arm
placement.
[0061] In another embodiment, the first band can be attached around
the wrist and the second band can attach to the racket. The first
sleeve, the second sleeve, and the first and second magnetic
components, can join the wrist to the racket. When in use, the
tennis training device can hold the wrist and the racket at
approximately a 90-degree angle. When the wearer drops the racket
downwards relative to the wrist, the releasable connectors may
detach from each other, letting the player know that the racket is
dropping and the wrist is getting flimsy. As will be understood,
the forearm and upper arm device can be worn in combination with
the wrist and racket device to cure both problems with arm
placement and timing during the swing.
[0062] In some embodiments, the disclosed systems and methods can
be adapted for improvement of a backhands groundstroke. The first
band can be configured to be worn around the torso of a player. In
some embodiments, the first band can be worn on an upper portion on
the torso, proximate the armpits of the player. The second band can
attach to the racket on the side of the racket's throat. When used
to improve a backhands groundstroke, the device will stay intact
until the player starts the backhands groundstroke with her hips,
at which point the releasable connector will disconnect.
[0063] Additionally, in some embodiments, where a player may be
turning too far while executing the backhand groundstroke, the
first and second sleeves can be worn across the player's body. For
instance, if the player is right-handed and holding the racket in
her right hand, the first band can be rotated about the player's
torso so that the first sleeve originates on the player's left side
and extends across the player's body towards the player's racket.
Such a configuration can prevent the player from overturning so as
to mess up the angle of her shot and lose the ability to strike the
ball cleanly.
[0064] Embodiments of the present disclosure can assist players in
training for a proper two-handed backhands stroke. The most
reoccurring problem in the two-handed backhands stroke is a player
overturning her body prior to engaging in the swing. For training a
player for proper preparation and timing of the two-handed
backhands, the described devices can attach around the right or the
left arm of the wearer. Generally, the device can be worn on the
right arm if the player pulls her one or both of her arms back too
far, which is a greater problem in one-handed backhands as opposed
to two-handed backhands. Further, the invention can be used as a
feedback tool for a particular type of backhand in which the player
first lowers her hands and racket on the first step, resulting with
the player facing sideways, and then lifting her hands as the
player steps into the stroke. When used for a two-handed backhands,
the player can focus on detaching the releasable connector on the
first step and re-attaching it on the second step.
[0065] As discussed in the embodiments described above, the first
band can attach around the upper arm and the second band can attach
around the forearm. When the second step ends, the player can start
to swing with the hips and the releasable connector can disconnect
to permit the arms to flow through the swing. In some embodiments,
the player may also wear a wrist and racket connection which should
stay connected throughout the preparation until the player starts
the swing with the hips.
[0066] Embodiments of the present disclosure can be adapted for use
during a serve. For instance, the described systems and devices can
also be used as a feedback tool for serves much in the same way as
it is used for the type of backhand discussed above and may be
attached when the player is starting to serve. In some embodiments,
the first band can attach around the upper arm and the second band
can attach around the forearm. When the player starts transferring
her weight backwards, the releasable connector can detach. As the
player starts transferring her weight forward, the releasable
connector can attach automatically after which the player can push
up with her legs to start the service motion.
[0067] Optionally, the player can keep the invention connected
until she pushes up with her legs. The former is for a more
traditional service motion. The latter is for a more abbreviated
motion.
[0068] Embodiments of the described tennis swing timing device can
also be used to learn a backhand slice. During preparation of the
swing, the magnetic components can remain attached. If the player
keeps the magnetic components intact until the swing starts, the
player will have kept the weight of the racket in position to work
properly for the swing.
[0069] Embodiments of the described tennis swing timing device can
be used to assist with a backhand volley. In some embodiments, the
first band can attach to the upper arm and the second band can
attach to the racket. In embodiments adapted for use during the
backhand volley, the first and second sleeves and the inner tubing
may be longer.
[0070] Forehand Groundstroke Device
[0071] Embodiments of the present disclosure can include a forehand
groundstroke device to assist players with learning, practicing,
and improving tennis forehand groundstrokes. In some embodiments,
the forehand groundstroke device can make it easier for a player to
generate downward momentum in the racket after starting to swing
with the hips. The disclosed forehand groundstroke devices can
efficiently and effectively guide the player to proper groundstroke
technique throughout the forehand swing, both in the swing's
preparation and the swing itself.
[0072] Embodiments of the forehand groundstroke device 400 can
comprise a first band 410, a second band 420, a resistance tubing
430, and an extension component 440. The resistance tubing 430 can
be adapted to connect between the first band 410 and the extension
component 440, and the extension component 440 can be adapted to
connect between the resistance tubing 430 and the second band 420.
In some embodiments, as illustrated at FIG. 4, the resistance
tubing 430 can optionally connect to the extension component 440
and the first band 410 via a plurality of rings 450. The plurality
of metal rings 450 can comprise metallic or plastic D-rings and can
be attached to the first band and the extension component in a
variety of ways. For example, and not limitation, the plurality of
rings can be stitched into the first band and the extension
component. In other embodiments, the extension component and the
resistance tubing can be looped through the D-rings. Yet, in other
embodiments, the resistance tubing can be tied or stitched to the
first band and the extension component without the plurality of
rings.
[0073] The resistance tubing can be adjustable in length. For
instance, in some embodiments, the resistance tubing can be looped
through the plurality of rings and tied, as illustrated at FIG. 4.
Therefore, the resistance tubing can be removed and replaced with a
longer or shorter resistance tubing as desired. As discussed above,
the resistance tubing can comprise surgical tubing of various
resistances and various diameters.
[0074] The extension component can comprise a variety of mechanisms
that provide for extending the resistance tubing to a point higher
on the wearer's body. For instance, in some embodiments, the
extension component can comprise a strap and buckle, as illustrated
at FIG. 4. Therefore, the extension component may be removable from
the device and replaced by another extension component that may be
a different size, shape, or structure. In some embodiments, the
extension component may comprise a rigid piece of tubing connected
between the second band and the resistance tubing. The rigid piece
of tubing may comprise some or all of the features as discussed
above with respect to the first and second sleeves shown in FIGS.
1A-3C.
[0075] In some embodiments, the first band 410 can attach around
the upper arm of a player, and the second band 420 can attach
around the upper leg (e.g., thigh) of the player, as illustrated at
FIGS. 5A and 5B. The extension component 440 can connect to the
second band 420 and the resistance tubing 430 can connect to the
extension component 440 and the first band 410. As will be
understood, the extension component 440 can elevate the resistance
band 430 proximate the wearer's waist. Elevating the resistance
band to a position proximate the wearer's waist can be advantageous
because an adequate downward force may be achieved when the second
band is located at a lower position, such as at the waist or on the
leg. If the second band is located too high on a player's body, it
may generate too much force in a horizontal direction. As such, the
second band can be attached anywhere on the leg including, but not
limited to, the upper leg of the player or the lower leg of the
player, below the player's knee. Finally, in some embodiments, the
device can comprise an additional resistance tubing connecting
between the upper arm band and a wrist or forearm of the wearer.
The additional resistance tubing can connect to the wrist or
forearm of wearer in a variety of ways including a third band or
simply typing the resistance tubing around the forearm or wrist of
the wearer.
[0076] Additionally, in an embodiment as illustrated at FIGS. 5A
and 5B, the resistance tubing can connect to a portion of the first
band located proximate a front portion of the player's arm. In
another embodiment, the resistance band can otherwise wrap around a
portion of the band located proximate a back portion of the
player's arm and connect to the first band proximate a front
portion of the player's arm. As discussed above, the resistance
tubing can connect to the first band via one or more rings.
[0077] In another embodiment of the forehand groundstroke devices,
the extension component is optional. For instance, the first band
can attach around the upper arm of a player, and the second band
attach around the torso of the player. The resistance tubing can
connect to the torso band on the right side of the wearer near the
rib cage and also to the upper arm band proximate the inner arm
part of the wearer. Therefore, when the inner tubing is connected
between the torso and the upper arm of the wearer, it can provide a
connection between the first band and the second band and
resistance to the player's arm as she executes a forehand
groundstroke.
[0078] As will be understood by persons skilled in the art, the
forehand groundstroke device can be worn in both a right-handed
configuration and a left-handed configuration. For instance, in
embodiments comprising an upper arm band and an upper leg band, if
a player is right-handed, the upper arm band can attach around the
right arm and the upper leg band can attach around the right leg of
the player. In an alternative embodiment for left-handed players,
the upper arm band can attach around the left arm of the player and
the upper leg band can attach around the left leg of the
player.
[0079] During proper use of the forehand groundstroke device, the
player's elbow can lift when the player turns sideways to hit the
ball, which builds up resistance in the surgical tubing. Then, the
player must maintain the resistance as she steps into the shot and
the hips start to rotate. After the player rotates her hips, she
can release the resistance. When the resistance is released, a
downward force can be applied to the arm, and thus, to the racket.
Then, in the follow-through, the player can feel the resistance in
the tubing build again. The resistance building here indicates that
the player used the hips and allowed the swing properly.
[0080] It is understood that the various components of the forehand
groundstroke device can share the same properties, materials, and
configurations described with respect to the tennis swing timing
device above. Additionally, the foreground groundstroke device can
be worn in conjunction with the other devices described herein.
[0081] Groundstroke Preparation Devices
[0082] For proper groundstrokes, the body must work in a particular
sequence to hit a tennis ball properly. The disclosed devices can
train a player to develop a feel for the proper sequence of
movement to achieve a proper groundstroke, the sequence including a
swing originating from the body and hips rather than the arm. The
necessary sequence for proper groundstrokes therefore begins with
the upper body and the hips. However, for many players, it is
intuitive to reach their arms back during preparation thereby
disconnecting their arm from their body. The disclosed device can
improve arm placement during groundstroke preparation by enabling
the user to keep her arm close to her body. By keeping the arm
connected, the player can now start the swing with her body and
hips rather than her arm.
[0083] As illustrated at FIG. 6, a groundstroke preparation device
600 can comprise a first band 610 and a second band 630. The first
band 610 and the second band 630 can each comprise an adherent
component 620a, 620b attached proximate the center of the first and
second bands 610, 630 with each component oriented towards the
other. Additionally, an insert 640 can be disposed within the
second band 630. In some embodiments, and as illustrated at FIG.
7A, when a player wears the groundstroke preparation device 600 the
insert 640 can extend from the second band 630 and towards the
first band 610. The insert can be advantageous as it can provide
the player with added flexibility when preparing for a
groundstroke. For instance, in a configuration as illustrated at
FIGS. 7A and 7B, where the first band 610 is worn on the player's
arm and the second band 630 is worn on a player's torso, the insert
640 can provide a player with additional space between her arm and
her torso. Additionally, the insert can comprise any material
including but not limited to foam, including high-density foam,
polyethylene foam, closed-cell polyethylene foam, soft plastics,
and beading.
[0084] The adherent components can be any type connector that
provides a releasable connection between the first band and the
second band. For instance the adherent components can comprise a
pair of magnets, snaps, or hook and loop fasteners (e.g. Velcro).
In an embodiment where the adherent components comprise magnets,
the connection between the first and second bands can be
established automatically, as described above regarding the tennis
swing timing device. In another embodiment where the adherent
components comprises a hook and loop fastener, the device can
provide the player with auditory feedback if the connection between
the first and second bands is broken.
[0085] Additionally, in an embodiment where the adherent components
comprise a pair of magnets, the magnets can be strong enough to
guide the user into the proper motion but weak enough to allow the
player to break the magnets apart when she starts to swing. It is
understood that the magnets can come in a variety of shapes and
strengths, as discussed above with respect to the tennis swing
timing device.
[0086] In some embodiments, the device for improving arm placement
during preparation for a groundstroke can be worn by a player in
the following way, and as illustrated at FIGS. 7A-7C. The first
band 610 can attach around the upper arm of the player, and the
second band 630 can attach around the torso of the player. When
worn together, the first band 610 and the second 630 band can be
worn at approximately the same level as each other, such that once
the player's arm is in the proper position, the adherent component
on the first band and the adherent component on the second band can
connect together and hold the player's arm in place proximate the
player's torso, as illustrated at FIG. 7A and 7C. When in use,
proper swing preparation can be achieved if the magnets stay
connected until the swing begins with her upper body or her hips.
Therefore, once the player begins to rotate her hips, the magnets
can break apart to allow her to complete the swing, as illustrated
at FIG. 7B. Therefore, for instance, the player can be provided
with feedback if her arm is in the proper position during swing
preparation. For example, if the adherent components comprise a
pair of magnetic components, the magnetic components can remain
connected until the player begins to swing with her upper body and
